To all whom it may concern."

Be it known that 1, ROBERT H. BEAUMoN'r,

a citizen of the United States, residing in ltadnor, Delaware County, Pennsylvania, have invented certain Improvements in Take-Ups for Skip-Hoist Hopes, of which the following is a specification.

One object of my invention is to provide a simple and effective means for taking up the slack in hoisting ropes, especially ropes used for operating skip hoists, in which one end of the rope is attached to the bail of a bucket.

A further object of the invention is to provide means for firmly holding the rope end to the adjustable sheave.

These objects I attain in the following manner, reference being had to the accompanying drawings, in which:

Fig. 1 is an end view of a skip hoist bucket to which my invention is applied;

Fig. 2 is a side view of the bucket;

Fig. 3 is an enlarged sectional view through the bail of the bucket on the line 33, Fig. 4:; i

Fig. 4: is a sectional view on the line H, F ig. 3;

Fig. 5 is a sectional view on the line Fig. 3; and

Fig. 6 is a side view of a tool for op erating the take-up device.

Referring to the drawings, 1 is the bucket of a skip hoist having a bail 2 consisting of a cross member 3 made of two channel beams connected to links 1 at the bottom of the bucket by side members 5. 6 is the hoisting rope, which is attached to a sheave 7 adjustably secured to the beams 8 of the cross member by bolts 9, which extend through holes in the beams and holes in the sheave. The hub 10 of the sheave extends through openings in the beams. In the hub is a rectangular (or other shaped) opening 11 to correspond with the shape of the tool 12 by which it is turned. This tool is shown in Fig. 6 and has a handle 13.

The sheave has a wide rim 14 for the rope. This rim is flanged at 15. 16 is a web connecting the rim of the sheave to the hub. In the rim is an opening 17 through which the rope passes. The end of the rope is coiled around the hub and is secured to the web 14 by U-shaped clamp bolts 18. On the web 16, on each side of the clamp bolts,

are ribs 19, which act with the bolts to secure the rop firmly to thesheave.

Four clamp bolts are shown, but it will be understood that one or more bolts may be used, depending upon the size of the bucket and its load. There are four sets of holes 20 for the passage of the locking bolts 9 so that, when the tool is inserted in the hole 11, the bolts 9 can be withdrawn to allow the sheave to be turned on its pivot to take up the slack of the rope, or to alter the position of the bucket. After the sheave is adjusted, the bolts can be placed in position, securing the sheave to the beams.

21 are rope guards, which are secured to the beams on each side of the rope.

By the above construction, it will be seen a very simple yet substantial take-up for ropes is provided, which can be easily mounted on the bail of a hoisting bucket.

I claim:

1. The combination in a rope take-up, of a support; a sheave mounted in said support; means for adjustably securing the sheave to the support; an opening in the run of the sheave; and a rop clamp for clamping the end of a rope which extends through the opening in the rim of the sheave.

2. The combination in a rope take-up device, of a support; a sheave having a rim, web and a hub, said hub being mounted in the support; means for adjustably securing the sheave to the support, the rim having an opening; a clamping device on the web; and a rope extending around the sheave and through the opening in the rim, the end of the rope being engaged by the clamping de v1ce.

3. The combination in a rope take-up device, of a support; a sheave having a rim, Web and hub, said hub being mounted to turn freely in the support; a series of holes in the sheave and support; bolts extending through said holes to secure the sheave to the support, the rim having an opening therein for the passage of a rope; and a series of clamps on the web for securing the end of the rope to the sheave.

4. The combination of a bucket; a bail having a cross member consisting of two beams spaced apart; a flanged sheave located in the space, the hub of the sheave having its bearings in the beams; bolts exmounted in the support andhaving an opening therein to receive a tool by which it can be turned; means for adjustably (securing the sheave to the support, the rim of the sheave having an opening forthe' passage of a rope; and aseries of U-shapedclam'ps secured to the Web of the sheave and engaging the rope.

6. The combination in a take-up for skip bucket hoisting ropes, of a bucket; a bail therefor having two cross beams; a flanged sheave located between the beams, the hub of the sheave extending into bearing openingsin the beams; bolts extending through the beams and the sheave, the hubof the sheave being shaped to receive a turning tool, the rim of the sheave having an openingtfor the passage of a rope; and a series of clamps on the web of the sheave, each clamp having a rib on each side for engaging the rope.
